[Also in Division B7] Operation of a first monostable device resets a counter which is being fed with pulses and sets a bi-stable device to enable an AND-gate to pass a signal from the counter when it reaches a predetermined count, and when the counter reaches another predetermined count it resets the bi-stable device and triggers a second monostable device. In a railway vehicle, the first monostable device is operated manually and the pulses fed to the counter are produced by movement of the vehicle. Three lamps are energized through AND-gates (including the one above) to indicate different distances travelled after manual operation of the first monostable device. Triggering of the second monostable device (destination reached) actuates a bell, horn, main switch or brake valve. In a modification, opening of the dead-man's switch resets the counter and stops the train, and (provided the bi-stable device is not set) actuation of the controller or brake valves resets the counter.

A method of working, for example sawing, timber comprises passing each timber unit to be worked to examining means for automatically determining the quality and/or dimension of the timber unit, and advancing the unit to a timber working station provided with a plurality of adjustable timber working members and working the unit thereat, the members being adjustable in accordance with control signals from a computer which obtains information signals from the examining means and which is so programmed that the required yield of worked timber is obtained from each timber unit according to its quality and/or dimensions. In apparatus for carrying out the method, a timber unit in the form of a log 1 is fed along a conveyer 2 to debarking apparatus 3 and a detector 4 which actuates ejector apparatus 5 if it detects a foreign body, such as a stone or metal object, to pass the log laterally on to a conveyer 6. If the log is free from foreign bodies, it is passed to a radioscopic device 7 which determines the quality of the log and feeds the information to a computer 12. The log is moved transversely on a conveyer 8 to toothed wheels 9 which are operated to rotate the log to its best position for cutting. The ends of the log are then engaged by grippers 10 which carry the log through a photo-electric gauge 11 which also feeds information to the computer 12. From the gauge the log is passed between band saws 16 the distance apart of which are controlled by a unit 13 operated by the computer. The trimmed pieces from the log pass along a conveyer 17 to saws 18, 19 which edge the pieces. The log, after trimming by the band saws 16 is now in the form of a block 20 which is then passed between band saws 22 controlled by a unit 14 operated by the computer, the trimmed pieces from the saws 22 being passed along the conveyer 17 to the saws 18, 19. The cut block 20 is sawn into planks by a band saw 23 controlled by a unit 15 operated by the computer.

Title: Improvements relating to apparatus for dispensing beer and like liquids
Inventor: PERKINS MICHAEL JOHN
IPC: B67D1/00
Filed: 1963-10-30
Abstract: 1,016,096. Delivering measured quantities of liquid. WOOD & PERKINS Ltd. Jan. 25, 1965 [Oct. 30, 1963; April 9, 1964], Nos. 42753/63 and 14653/64. Heading B8N. An apparatus for dispensing measured quantities of liquid such as beer comprises a measuring chamber 16 adapted for connection separately to a source of supply and a reservoir 42, and means 21, 22, 18, 19 for closing communication between the measure and both the source and the reservoir prior to dispensing. The means for closing communication between the source and the chamber is in the form of a valve 21 adapted to co-operate with a seat 22 and actuated by means of racks 26 and pinions 24 secured to a shaft 25 which can be rotated by a handle 15. A valve 18 loaded by a spring 30 is arranged to co-operate with a seat 19 in order to close communication between the chamber and reservoir. An outlet valve 31 is provided and is adapted to slide over an outlet pipe 32 communicating with a spout 12 via an aperture 37. In operation, with the apparatus in the position shown, beer under pressure is fed via an inlet pipe 13 into the chamber where it rises into the reservoir up to the line 23. To dispense the beer, the handle 15 is rotated thereby causing the valve 21 to abut its seat 22, continued movement of the handle then causing the chamber 16 itself to move downwardly so that the seat 19 abuts the valve 18 and closes communication between the chamber and reservoir. Further downward movement of the chamber causes a shoulder- 33 in the valve 21 to abut the outlet valve 31 and so permit the beer to flow through the outlet pipe and spout. During the dispensing operation, pressurized gas is fed into the reservoir via a pipe 14 and a now opened valve 39 to act on the beer as it is being dispensed thereby preventing frothing. In order to prevent the flow of beer being stopped before the contents of the chamber has been completely dispensed, the handle 15 is connected to the shaft by a clutch device 45, 46 actuated via a diaphragm 50 connected via a valve 52 with the pressurized gas supply; if the handle is rotated prematurely, it only freewheels on the shaft. At the end of the stroke when the gas pressure drops, the clutch operates so that the apparatus can be returned to its initial position. The surfaces of the apparatus in contact with the beer are coated with P.T.F.E.
